5. Installing the unit

5.1. Hanging the unit body
 Bring the indoor unit to an installation site as it is packed.
 To hang the indoor unit, use a lifting machine to lift and pass through the
hanging bolts.

Refer to the Instruction Manual that came with the outdoor unit for the restrictions on
the height difference between units and for the amount of additional refrigerant
charge.
Avoid the following places for installation where air conditioner trouble is liable to
occur.
• Where there is too much oil such as for machine or cooking.
• Salty environment as seaside areas.
• Hot-spring areas.
• Where sulfide gas exists.
• Other special atmospheric areas.

Hanging structure
• Ceiling: The ceiling structure varies from building to one another. For detailed
information, consult your construction company.
• If necessary, reinforce the hanging bolts with anti-quake supporting members as
countermeasures against earthquakes.
* Use M10 for hanging bolts and anti-quake supporting members (field supply).
a Reinforcing the ceiling with additional members (edge beam, etc.) must be
required to keep the ceiling at level and to prevent the ceiling from vibrations.
b Cut and remove the ceiling members.
c Reinforce the ceiling members, and add other members for fixing the ceiling
boards.

5.2. Confirming the unit's position and fixing hanging
bolts
 Ensure that the hanging bolt nuts are tightened to fix the hanging bolts.
 To ensure that drain is discharged, be sure to hang the unit at level using a
level.
Caution:
Install the unit in horizontal position. If the side with drain port is installed
higher, water leakage may be caused.
• This unit has brazed connections on both indoor and outdoor sides. [Fig. 6-1]
• Insulate both refrigerant and drainage piping completely to prevent condensation.
Piping preparation
• Refrigerant pipes of 3, 5, 7, 10 and 15 m are available as optional items.
(1) Table below shows the specifications of pipes commercially available.

(2) Ensure that the 2 refrigerant pipes are well insulated to prevent condensation.
(3) Refrigerant pipe bending radius must be 10 cm or more.
Caution:
Using careful insulation of specified thickness. Excessive thickness prevents
storage behind the indoor unit and smaller thickness causes dew drippage.
Warning:
To reduce the risk of fire, embed or protect the refrigerant pipes. Damage to
the refrigerant pipes can lead to fire.
